AUTOMATIC WElGHlNG-MACHINE.

Specification of Letters Patent.

Patented Nov. '7, 1905.

To all whom it inf/Ly concern.-

Beit known thatl, GEORGE W. LOTTRIDGE, residing at Niles, Berrien county, Michigan, have invented certain new and useful Improvements in Automatic VVeighing-h/Iachines, of which the following is a specification.

My invention relates to machines for automatically weighing different articles, more particularly what are known as packaged articlessuch as cereal foods, sugar, starch, eofi ee, and the like; and my object is to provide a simple, efficient, and reliable machine of this character whose features of advantage and utility will be apparent from the description hereinafter given.

In the drawings, Figure 1 is a side elevation of my weighing-machine; Fig. 2, a rear elevation thereof; Fig. 3, a sectional elevation on line 3 3 of Fig. 1; Fig. 4:, a plan view of the machine; Fig. 5, a sectional plan view taken along line 5 5 of Fig. 1 with the spout removed; Fig. 6, asectional elevation on line 6 6 of Fig. 5; and Figs. 7 and 8, enlarged detail views of the operating mechanism of the machine, showing the parts of such mechanism in different relative positions.

As herein shown, my weighing-machine is provided with a main frame 1 for carrying and supporting the various operating parts, including the supply-hopper 2, weighing-hopper 3, and receiving-hopper 4, all arranged and cooperating in the manner hereinafter explained. The frame 1 is extended upwardly above the level of the weighing-hopper and terminates in a ring 5, adapted to receive and support the supply-hopper, as clearly indicated in Figs. 1, 2, and 3. The lowermost or receiving hopper A is connected to the main frame by the bracket-frame 6, which is secured to such main frame in suitable manner.

The weighing-hopper is a movable one, being pivotally supported on the free ends or arms of a U-shaped or bifurcated scale-beam 7, which is itself pivoted to the main frame at the points or bearings 8. The cross-bar member 9 of this U-shaped scale-beam is provided with a rearwardly extending portion 10, adapted to carry the weights 11, which may be adjusted thereon to weigh up the necessary weight of the article in the weighinghopper. The downward movement of the rear end of the scale-beam is limited and stopped by contact with a rod or support 12, extending vertically upward from the baseof the main frame, Fig. 1, while upward movement is limited by the adjustable bolt 13, depending from the main frame into the path of movement of the cross-bar 9 of the scalebeam. By adjustment of this bolt up or down the range of movement of the scale-beam, and consequently the vertical movement of the weigliing-ho iper, maybe regulated. To prevent swaying of the weighing-hopper and steady its movements, a stay-link 11 is provided, the same being pivoted at one end to the rear side of such hopper and at its other end to a depending bracket or arm 15, secured to the main frame, Fig. 1.

The weighing-hopper is in the present instance rectangular and divided into two separate compartments 16 and 17 by means of a transverse partition 18, Figs. 3, 4:, and 5. By preference this partition is provided at its lower end with two oppositely-directed branches or flanges 19, as best seen in Figs. 3 and 4. The compartments 16 and 17 of this hopper have movable and laterally downwardly inclined bottoms 20 and 21, respectively. These bottoms are connected together and arranged to rock on a transverse axis 22. The inclination of these bottoms is such that when one of them is in closed position to close its compartment the other is in open position, as shown in Fig. 3, wherein the bottom 20 is illustrated in closed position and bottom 21 in open position. ings 23 project upwardly from the sides of the bottoms and extend along the outer faces of the front and rear sides of the weighing-hopper for the purpose of forming chutes in connection with the bottoms to laterally deliver the weighed articles.

The articles are designed to be weighed in and delivered from the compartments alternately in automatic manner, and to this end the following mechanism is provided: A frame or plate 24: is secured to the wings 23 on the rear side of the weighing-hopper, and therefore is adapted to rock on the same axis 22. To this rocking plate are pivoted the two latches 25 and 26, extending laterally in op posite directions and provided, respectively, on their lower edge with the notches 27 and 28. These latches are arranged to slide between the guide-fingers 29 and 30, respectively, which fingers are adapted to engage and retain its latch whenever the latter has reached its extreme lateral or outward movement, with the result that swinging bottoms of the latches on their downward movement.

' ing-machine I will describe a complete cycle of are held or locked in one position or the other. In order to automatically trip and release the latches from their locked position in the downward movement of the weighing-hopper, I provide a pair of dogs 31 and 32, which are arranged in the path of movement of the latches when shifted to their extreme outward position. These latches are pivoted to depending arms or brackets 33, arranged adjacent opposite sides of the weighing-buckets, as shown in Figs. 1, 4, 7, and 8. These dogs are free to 'rise to let the latches pass upward Without interference, but trip one or the other The latches are limited against excess movement by the springs 34.

Below the delivery end or spout 2 of the supply-hopper 2 is arranged a spout or chute 35, which is arranged to oscillate in such manner as to divert the stream of the article to be weighed from one compartment or bucket to the other. In the present instance this spout is secured to a pivoted frame 36, having a downwardly-extending pivoted pin 37 passing through the top cross-bar 38 and bearing in the lower cross-bar 39, all as clearly illustrated in Figs. 5 and 6. This pivoted frame is provided with two forwardlyextending fingers 40, between which operates the vertical lever 41 for shifting the spout 35. Referring to Figs. 7 and 8, this lever is pivoted at 42 to the rear side of the weighingbuckets and is operatively connected at its lower end with the swinging frame 24, hereinbefore described. To compensate for the relative movement of the parts, the lower end of this operating-lever 41 has a pin or stud 43 adapted to work in a slot 44 in the frame 24.

To steady the movement of the spout 35 and hold it with a frictional resistance, the top cross-bar 38 is extended rearwardly and provided with a quadrant portion 45, beyond and parallel with which are arranged two flat springs 46. The pivoted frame, which carries the spout 35, has a rearwardly-extending arm 47, whose extreme free end 48 is downwardly bent or formed so as to play over the quadrant between the limits of the two stops 49, Figs. 1,2, 4, and 5. This end 48 of the arm 47 slides upon the flat springs clescribed and is thereby held with a frictional resistance.

In explaining the operation of my weighmovements of the partsthat is, the automatic filling, weighing, and discharging of the article in both weighing-buckets. Starting with the parts shown in Fig. 3, the supply-hopper 2 delivers a continuous stream of the article upon the spout 35, which is in position to divert such stream into the left-hand bucket or compartment 16. The filling continues until the weight of the contents of such bucket 1 reaches the amount determined by the weight I or the adjustment thereof on the scale-beam. 1

The entire weighing hopper or bucket then begins to descend, with the result that the latch 25 is tripped by its dog 31, whereupon the weight of the article upon the bottom 20 will swing the entire bottom structure, opening such bottom 20 to deliver the contents of bucket 16 to the IGCOlVlUg-llOpDGl 4 and by the same movement closing the other bottom 21, so that the bucket or compartment 17 will be ready to receive the article to be weighed. At the end of this movement the latch 26 hooks over the base of the guide-fingers 30 and locks the parts in such shifted position. The movement of the parts as just described also causes an oscillation of the frame 24, which is secured to the bottom structure, whereby the lower end of the upright operating-lever 41 is shifted laterally in one direction, while its upper end is shifted in the opposite direction, with the result that by the contact thereof with the fingers 40 the spout is shifted so as to divert the stream from the bucket 16 to the bucket 17, Fig. 8. During the time of the emptying of the bucket 16 the weighing-hopper rises, owing to the release of its contents; but in its upward movement the latch 26 slips by the dog 32 and assumes a position above such dog. \Vhen the bucket 17 is filled to the predetermined extent, the weighing-hopper descends, and as soon as the latch 26 is tripped by its dog 32 the weight of the contents pressing upon the bottom 21 swings the latter open, simultaneously closing the bottom 20 and shifting the spout 35, so as to divert the article into the bucket 16 again. The parts again assume the relative position shown in Fig. 7, and in rising the latch 25 slips by its dog 31 and takes its position above such dog, ready to be tripped thereby on the descent.

The operation above described continues so long as the article to be weighed is delivered to the machine. The operation is thus both a continuous and an automatic one, weighing up the predetermined weight of the article and delivering it into a receiving-hopper,

from which it may be run into packages which are brought below the spout of such hopper, as by an endless conveyer or the like.

In order to secure such nicety and accuracy of adjustment as could not be conveniently obtained ordinarily through the medium of the set-screw cooperating with the weight 11 of the scale-beam, I have made the weight in two sections, the outer section or. member 11 being arranged to screw upon the outer end of the main member or section, with the result that the member 11 may be screwed or unscrewed with reference to the main member 11 and the parts held in the proper adjusted position by means of a set-screw 11". The main member or section of the weight 11 is arranged to be held to adjusted position on the rod 10 in suitable manner, as by means of the set-screw ll.
